 Notes:
 1) Thread must be embedded in a rafter or other structural roof member.
 2) See IBC for required edge distances.
 **Note: To maintain waterproofing it is important that the aluminum flashing is properly placed under one full course above the mounting block with at least some of the flashing extending
 up under the course above that as well. See instructions on back.
